Minkowski's second theorem, which is a key result in the theory of convex bodies in the context of number theory and geometry, pertains to the volume of convex symmetric bodies in Euclidean space and their relation to lattice points. The theorem states that if \( K \) is a convex symmetric body in \( \mathbb{R}^n \) (i.e.
High-temperature superconductors (HTS) are materials that exhibit superconductivity at temperatures significantly higher than traditional superconductors, which require cooling to near absolute zero (around -273.15°C or 0 Kelvin). Superconductivity is the phenomenon where a material can conduct electricity without resistance, allowing for the lossless transport of electric current. HTS materials typically become superconducting at temperatures above 77 Kelvin (-196°C), which is the boiling point of liquid nitrogen.
Thermal conductance quantum refers to a quantized unit of thermal conductance, usually expressed in the context of nanoscale and mesoscopic systems where quantum effects become significant. In these systems, heat transfer does not necessarily follow classical laws, and the discrete nature of heat carriers can lead to interesting phenomena.
The COVID-19 pandemic had significant and multifaceted impacts on public transport systems around the world.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
